7 Claims.

This invention relates to new and useful improvements in fountain pens and more particularlyl ity pertains to fountain pens of the type which employ more than one color of ink and which are capable of writing at will with any of the particular colors of ink.

It is an object of the invention to provide a fountain pen in which at least two different colors of ink may be employed and in which either color may be used independently ofthe other color.

A further object of the invention resides in a `new and novel construction and arrangement of parts whereby the inks are maintained separately at all times with no possibility of their intermingling.

Still a further object of the invention resides in a novelconstruction of filling means whereby the ink reservoir may be independently filled by a mechanism which may be independently connected with each reservoir for operation.

With the above and other objects in view, reference is had to the accompanying drawing,

wherein; f

Referring more particularly to the drawing, the pen comprises-a barrel section lil, which barrel section til is divided longitudinally by a partit-ion Il to form two ink reservoirs l2 and i3. The rear end of the barrel section is closed by a wall it which has two passages l5 and l5 therethrough. The forward end of the barrel it! is closed by a wall i9, and passing therethrough @there are two tubular members Il and i8 which extend toa point closely adjacent the rear wall M of the barrel Il). When the parts are in their assembled position, the tubular member il' will be substantially in line with the passage E5 and the tubular member i8 will be substantially in line with the passage it of the wall ifi, and the upper end of each of these tubes is flared as at 25. The purpose of this construction will be hereinafter described.

Carried by the forward end of the tube ll, there is a semi-circular tubular member 22'., and carried by the forward end of the tube it, there is a similar member 23. These members are spaced with respect to each other, as illustrated in Figure el, and as best illustrated in said figure, the tubular members l'l and l are of such diameter as to form a tight friction fit between th curved wall and the straight wall of their respective forward tubular member 22 or 25 where they are engaged therewith. This construction provides spaces 2B upon opposite sides of the t tubular members El and i8 through which the ink may flow from the reservoirs l2 and i3 into the forward tubular members 22 and 2s, respectively.'

As best illustrated in Figure 2, the tubular members Vi and lil terminate at a point short of the forward end of their respective tubular mem" bers 22 and 23, as illustrated at Edin Figure 2, and this construction provides a relatively small space 2l between the ends of the tubular mema bers ll' and i8 and the forward ends of their respective tubular members 22 and 23.

Carried by the tubular extensions `22 and 23, there is a sleeve member 3G, best illustrated in Figures 6 and 8. This sleeve member is cut out i as at 3i and 32 to provide leg extensions 33 which are spaced from each other. This sleeve is of such a diameter thatit has a friction t with the tubular members 22 and 23, which friction fit will be sufficient to retain it in either of the .4

adjusted positions to which it is moved and which will be hereinafter described.

The writing nibs or points are designated it and 60 and they are carried by a block 4I, which block ll has two angularly disposed passages i2 and 43 which lead respectively to the feed bars it andt of the writing nibs or points 4U and 49. Each of these passages l2 and 43 terminates in a nipple i, and these nipples lili are adapted to be received in openings il in the inner flat faces i8 of the leg extensions 22 and 23, this construction being shown in Figure 8. The marginal edges of the openings dl are flanged, as best illustrated at 49 in Figure 6, and the nipples 46, heretofore mentioned, cooperating 1 with the flanged edge of their respective opening 4`I form a liquid tight joint between the block 4I and the tubular leg extensions 22 and 23, thus assuring that there is no leakage of ink at this point. In addition to providing a liquid tight joint, the construction just described provides for pivotally mounting the block 4I between the leg extensions 22 and 23 in order that the same may be rotated between the legs to move the writing nibs or points into and out of operative writing position, as illustrated by dotted and full line positions in Figure 7 of the drawing.

With the parts in the position in which they are shown in Figure 2, ink will feed from the reservoir I3 to the tubular leg 23, from which it will pass through the passage V43 to the feedbar 45 of the writing nib or point 40. If, however, the block 4I be rotated through 180, the feed bar 44 would then be moved to the forward posi- .tion and the ink would feed from the reservoir I2 to the tubular leg extension 22 through the passage 42 to the feed bar 44 of the other writing nib or point 40.

The reference numeral 50 designates a bolt which is threaded as at 5| into a bushing carried-by the rear wall I4 and rotatably mounted upon this bolt 50 there is a disk like member 52 which has a passage 53 therein. This passage 53 is adapted to be brought into registration with either of the passages I5 and I6 for a purpose to be now described. The member 52 has an extension 54 which carries a compressible sack 55 which is adapted when collapsed and' allowed to refill, to draw ink into either of the reservo-irs I2 or I3 as the case may be. With the parts in the position in which they are shown in Figure 2, if the feed bar 45 be submerged in a receptacle of ink and the sack 55 collapsed, air will be forced from the sack 55 through the passages 53 and I6, the reservoir I3, tubular member I8, passage 43, and in this manner discharged from the pen. Upon release of the collapsible sack 55, ink will be drawn in through the feed bar, passage 43, and into the tubular leg extension 23. A few such operations will completely ll the reservoir with ink, after which the member 52 is rotated so `that its passage 53 will be out of registration with the passage 5I. Registration of the passage 53 with the passage I5 and operation as just described will ll the reservoir I2 with ink which obviously, would be of a different color. The member 52 may befprovided with suitable indicating means in the form of a notch 58 adapted to register with notches 59 upon the extension 6I) of the barrel Il] in order to indicate the proper position of the member 52 to have its passage 53 register with either the passage I5 or I6. A suitable cap 6I may have threaded engagement with the barrel III as at 62 to enclose the collapsible member when the same'is not in use, and a reversible cap 63 which carries the conventional pocket clip 54 is adapted for threaded engagement as at 65 of the barrel IIJ in order to enclose the writing end of the pen when not in use.

In order to rotate the block 4I through 180 as heretofore described, the sleeve member 38, heretofore mentioned, must be turned until the spaces 3I and 32 coincide with the space between the tubular leg extensions 22 and 23, in which position the block 4I is free to move through the spaces between the legs of the sleeve and the tubular members 22 and 23. After the blockrhas been rotated to the desired position to expose either of the writing nibs or points. the sleeve 30 is again rotated so that its extensions 3I and 33 will cover or enclose the open spaces between the tubular extensions 22 and 23, as best illustrated in Figures 4 and 5, in which position the block 4I will be held against movement about its pivotal points, and the pen exposed for writing will be rigidly held in writing position.

In order to retain the member 52 tightly upon the wall I4, a washer 'ED and a spring 'II may be interposed between the head 12 of the bolt 5|] and the upper face of the member 52. The bolt 5i) being anchored in the wall I4, and the spring II being under compression, a tight working t between the member 52 and the wall I4 will be had.

From the foregoing it will be apparent that the present invention provides a new and improved fountain pen in which at least two colors of writing uid may be employed and in which the choice of writing fluids may be made at will.
